Extra Production – at What Cost

Extra Production – at What Cost?

Under the present prices, farmers use milk substitutes for young calves instead of whole milk, discarded milk (antibiotic or with high SCC) excluded. This amount should be reduced, and
the breach of the biological security should not be underestimated, especially in herds that adopted any disease eradication programs.

Early Detection Of Clinical And Sub-Clinical Mastitis

Early Detection Of Clinical And Sub-Clinical Mastitis

Mastitis is the most costly disease affecting daily cattle. Losses occur from decreased milk production, treatment and labor costs, non deliverable milk, veterinary fees, reduced milk quality, reduced milk price, increased risk of subsequent mastitis, culling and death of the cow.

Fertility Report in AfiFarm program and efficiency of Estrus detection

Fertility Report in AfiFarm

The fertility reports of the Dairy Records Processing Centers in some countries, including Israel, contain data about distribution of the length of the cows’ cycles in the herd. The percentage of “double cycles” (36-60 days) indicates above all the efficiency of heat detection.
The lower the percentage of double cycles, the greater the efficiency of heat detection. According to the HACHAKLAIT – the cooperative society for veterinary services – the goal of Israeli dairy cows’ reproductive management is less than 18 percent of double cycles.

Detection and Prevention of Milking Routine Problems by Computerized Monitoring of Milking Irregularities

Detection and Prevention of Milking Routine Problems

A study was carried out to examine if computer monitoring of the dairy herd can help in the assessment of the milking routine on individual farms, to advise on possible shortcomings, and to monitor recommendations on improvements to the milking routine, particularly violations of “overriding” the ACR settings.

Dairy Management - Feed graph

The practice of body condition scores of dairy cows in Israel

Body condition score (BCS) allows the cattle producers to assess the nutritional status and the changes in the energy balance of cows during various production stages. The importance of evaluation of BCS for effective dairy management is well known.
The uniform BCS system was developed in 1989 by A.J.Edmondson and simplified in 1994 by J. Ferguson at the University of Pennsylvania. The cows are typically scored on a 5-point scale from 1 indicating thin to 5 indicating obese. Recently, the dairy extension veterinarian of Illinois University R.L. Wallace described in detail in “Hoard’s Dairyman” of September 25, 2000, “What condition scoring can tell you”.

Influence of milk yield and take-off settings

Influence of milk yield and take-off settings

The first aim of this study was to monitor parlour performance in high producing Israeli herds using the parameter proposed by Reid and Stewart (2007) for herds milked three times daily, 55 kg milk/stall/hour. Milk yield, somatic cell count and the culling rate were monitored correspondingly.
The second aim was to examine if by increasing manufacturers default take-off settings in Israel, there will be no detrimental effect on parlour performance and udder health (SCC).

Automated cow monitoring system

Automated Monitoring of Dairy Cows’

Automatically monitored behavioral (feeding and locomotor) irregularities of Israeli Holstein cows were investigated in three dairies in relation to animals’ health status and stress conditions. Feeding behavior patterns were analyzed on the base of automatic on-line recording of feeding events. Indices of feeding behavior irregularities were proposed.
Long lasted feeding behavior irregularities were accompanied by poor health related parameters: higher milk Somatic Cells Count and conductivity, greater body condition loss toward first insemination, and increased cooling rate.

Proper control brings positive returns (Stuart Mackenzie)

Proper control brings positive returns

“About three years ago I was in an aggressive expansion phase. For me to get a good quota, I had to get my cow numbers up quickly. When I got the chance to acquire an Ayrshire herd, I not only could up my milk production, but it also offered me the opportunity to differentiate a little bit in terms of the price I receive for my milk, Ayrshire milk being regarded as different from Holstein milk.”

Put your cows on auto control

Put your cows on auto control

The system makes it possible to take care of each cow individually, even if it is part of a very large herd. As a matter of fact, the larger the herd, the sooner the system will be able to “pay for itself”. The Afimilk dairy management system is a product of SAE Afikim, a company that has specialized in computerized systems for the modern dairy farm for the past 30 years.

Achieving high performance

Achieving high performance in dairy farms-Experience

Dairy farming has developed very fast in the last years in China. Many factors can influence the milk production of dairy cows, such as genetics, management, nutrition, improved technology, etc.
At SanYuan we managed to reach the highest milk production level in China in the last decade. The purpose of this article is to report our experience. Which were the main factors for this great achievement?
